Key inclusion & exclusion criteria

Inclusion criteria:
1. Male or female patients ages 6 years-17 years;
2. Written informed consent provided by the patient’s parent (or legal guardian) and
assent provided by the patient consistent with ICH/GCP and Local Institutional
Review Board requirements for children obtained prior to any study procedures being
performed;
3. Ability and willingness to comply with study treatment regimen and to attend study
assessments;
4. Diagnosed with Tourette’s Disorder as per the below DSM-IV criteria and with a
score =22 on the Total Tic Score (TTS) of the YGTSS at baseline:
• Both multiple motor and one or more vocal tics have been present at some time
during the illness, although not necessarily concurrently. (A tic is a sudden, rapid,
recurrent, non-rhythmic, stereotyped motor movement or vocalization.)
• The tics occur many times a day (usually in bouts) nearly every day or
intermittently throughout a period of more than 1 year, and during this period
there was never a tic-free period of more than 3 consecutive months
• The onset is before age 18 years
• The disturbance is not due to the direct physiological effects of a substance (e.g.,
stimulants) or a general medical condition (e.g., Huntington’s disease or post-viral
encephalitis)
• The disturbance causes marked distress or significant impairment in social,
occupational, or other important areas of functioning
5. Diagnosis of Tourette’s Disorder when administering the Diagnostic Interview
Schedule for Children (DISC-IV);
6. Women of childbearing potential must have a negative serum Beta-HCG pregnancy
test at the Screening (Baseline) visit unless surgically sterile;
7. Either a de novo patient (not on current treatment for TS), or a patient who has been diagnosed with TS, but who the investigator feels, has not been adequately managed using current therapy, or has failed current therapy, whereby the patient may benefit in the use of pramipexole and, if on current therapy, can be safely discontinued from such therapy prior to enrollment into this study;
8. Women of childbearing potential must be using a medically accepted contraceptive
method. Acceptable methods of birth control are limited to: Intra-Uterine Device
(IUD), oral, implantable, injectable contraceptives and estrogen patch, double barrier
method (spermacide + diaphragm), or abstinence at the discretion of the investigator;
9. Having a body weight =20 kg.
Are the trial subjects under 18? yes
Number of subjects for this age range:
F.1.2 Adults (18-64 years) no
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range

Exclusion criteria:
1. Any women of childbearing potential having a positive serum pregnancy test at
screening;
2. Clinically significant renal disease or serum creatinine out of this range: 0.3-1.0 mg/dL for patients aged 6-12 years and 0.5-1.4 mg/dL for patients aged 13+ years;
3. Any of the following lab results at screening:
? Hemoglobin (Hgb) below lower limit of normal (LLN) which is determined to be
clinically significant.
? Basal thyroid stimulating hormone (TSH), triiodothyronine (T3) or thyroxine (T4)
clinically significantly (at the investigator’s discretion) out of normal range at
screening (if not caused by substitution therapy according the investigator’s
opinion).
? Patients with any clinically significant abnormalities in laboratory parameters at
screening at the investigator’s discretion.
4. Other clinically significant metabolic-endocrine, hematological, gastrointestinal
disease, pulmonary disease (such as severe asthma) in the opinion of the investigator which would preclude the patient from participating in this study;
5. History of schizophrenia or any psychotic disorder, history of mental disorders or any present Axis I psychiatric disorder according DSM IV (using the DISC-IV assessment interview) requiring any medical therapy except for TS, except for patients with a diagnosis of ADHD or OCD who are not on therapy;
6. History of/or clinical signs of epilepsy or seizures other than fever related seizures in early childhood;
7. History of/or clinical signs of any malignant neoplasm including suspicious
undiagnosed skin lesion (which may be melanoma), melanoma, or a history of
melanoma;
8. Any other conditions that in the opinion of the investigator would interfere with the evaluation of the results or constitute a health hazard for the patient;
9. Allergic response to pramipexole or the inactive ingredients in its tablet formulation;
10. Had previous treatment with dopamine agonists other than pramipexole within
14 days prior to baseline visit;
11. Had any other medical treatment for TS besides the study medication within 28 days prior to baseline visit (14 days for guanfacine and clonidine; 14 days for dopamine agonists; 14 days for L-Dopa);
12. Had withdrawal symptoms of any medication at screening or at the baseline visit;
13. Having a K BIT2 IQ score <70 at screening;
14. Having a CY-BOCS score >15 at baseline;
15. Patients who meet criteria for Restless Legs Syndrome and/or Periodic Limb
Movement disorder;
16. Patients with a history of severe asthma or pulmonary complications. Patients with asthma that is well-controlled are not excluded;
17. Patients that have initiated psychotherapy for Tourette Syndrome, OCD or ADHD
within 3 months prior to starting the trial;
18. Patients receiving psychological, cognitive and/or behavioral treatments greater than 3 months prior to starting the trial for Tourette Syndrome, OCD and/ or ADHD
symptoms who will have changes in their treatment plan or treatment course during
the trial as well as those patients who will require the initiation of such treatments
during the trial.
19. Concurrent participation in another clinical trial or any investigational therapy within thirty days prior to start of this study.

Primary Outcome(s)

Primary end point(s): Change from baseline of the TTS of the YGTSS after 6 weeks of treatment.

Secondary Objective: Secondary efficacy measures:
